Oral treatment with genistein reduces the expression of molecular and biochemical markers of inflammation in a rat model of chronic TNBS-induced colitis

Background Inflammatory bowel disease (IBD) in humans has a high incidence in Europe and the USA, whereas in East Asia, incidence has been historically low. The risk of IBD appears to increase in Asian immigrants adopting western lifestyles, suggesting a strong link of environmental/dietary factors in the development of IBD. Exposure to high levels of isoflavones such as genistein (Gen) in traditional East Asian diets has been associated with a decreased risk of developing breast cancer and may also be beneficial for the prevention of IBD.
